Add High Availability backup

Fill in the fields, then click OK to activate high availability.

Port number
The number of a port that is unused on both Load Balancer machines that will be used for heartbeat messages. You must use the same port number for both the primary and backup machines.
Role
Choose between:
  • Primary: the primary machine sends connection data continually to the backup machine.
  • Backup: the backup machine is in standby state, continually updated and ready to take over if necessary.
  • Both (mutual high availability feature): if the backup machine detects that the active machine has failed, it will take over and begin load balancing. At that point the statuses of the two machines are reversed, the backup machine becomes the active and the primary becomes the standby.

Recovery strategy
Choose between:
  • Auto--the primary machine resumes load balancing as soon as it comes back into service.
  • Manual--the primary machine acts as standby for the backup machine and does not resume routing packets until the administrator issues a takeover command.

Heartbeat source address
The address of the high availability partner machine that sends heartbeats. This address should be defined on the physical adapter of the partner that you wish to use to monitor the health of the Load Balancer. You can define a source address for each physical adapter in the Load Balancer machine.

Heartbeat destination address
The destination address is the address of the high availability partner machine to which heartbeats and responses are sent. This address should be defined on the physical adapter of the partner that you wish to use to monitor the health of the Load Balancer. You can define a destination address for each physical adapter in the Load Balancer machine.
